The grocer wants £529 for the 7in, Android 2.2-based tablet with 2.4GHz 802.11n Wi-Fi, 3G, Bluetooth and GPS, the same price Apple wants for the 9.7in iPad with those same connectivity and navigation features. Both devices come with 16GB of storage, though the Tab has a memory card slot for more.

Earlier this week, O2 said it would offer the Tab, which can already be ordered from Amazon.co.uk, Carphone Warehouse and a number of other retailers. Vodafone and Three will sell it too but, like O2, have yet to say what they'll charge. ®
